Title: Electric power flow control
IPC: G05F1/66
Filed: 1974-05-10
Abstract: 1455054 Automatic control of power distribution BELORUS FILIAL GOSUDARST ENERGETICH INST IMENI G M KRZHIZHANOV 10 May 1974 20663/74 Heading G3R The active power flow in a transmission time is regulated by an integral or proportional plus-integral control depending on a comparison between a permissible power flow limit value and an extrapolated value of the maximum actual power flow calculated over a finite period forward in time. As shown, actual power flow P 1  is measured by a transducer 1 and compared in a circuit 2 with a desired value P 2  to form a difference signal #P 1  which is supplied to an adding circuit 8 over parallel paths including an integrator 6 and an amplifier 7 in series with a gate circuit 9 respectively. The resulting control signal P 4  is supplied to a further adding circuit 11 where it is combined with signals P 5 , P 6  representing desired and actual power station output levels to produce a turbine control signal #P 2 . The gate circuit 9 is controlled by a circuit 4 which calculates extrapolated probable values for the power flow according to a given formula involving time intervals produced by a sawtooth generator and compares a maximum extrapolated value with a permissible limit signal P 3 . If this limit value is exceeded by the calculated maximum value, a signal A is produced to actuate the gate 9, thus allowing a proportional signal component to be supplied to adding circuit 8. If the limit value is not exceeded, the gate remains closed and control is exercised solely by the integral signal through circuit 6.

Filed: 1928-07-17
Abstract: 315,569. Rawcliffe, G., and Pilling & Sons, Ltd., J. July 17, 1928. Take-up motions. - Relates to quarterchange wheel slip catches designed to let back automatically a predetermined number of picks on the breakage of the weft, and consists in mounting the slip catch on means which, when operated, cause the teeth of the slip catch to be withdrawn from the pick wheel without first rotating the pick wheel, whereby any further number of picks may then be let back. The slip catch 1 is rotatable on an eccentric sleeve 7 provided with a handle 10 and loosely mounted on a stud 6 adjustably secured in a bracket 15. When the handle 10 is moved against a stop 11, the teeth 12 of the catch are in full engagement with the teeth of the pick wheel 13, or the change wheel, but when the handle 10 is moved against a stop 14, the sleeve 7 is rotated thereby to move the teeth 12 in a substantially radial direction out of engagement with the teeth 13, so that any desired number of picks may then be let back. The stops 11, 14 are formed on a part which is secured to the stud 6 and serves normally as a stop for the arm 17 of the catch 1.

Title: Control devices for copying machines
IPC: B23Q35/32
Filed: 1939-07-17
Abstract: 532,167. Friction clutches. ROSEN, O. E. July 17, 1939, No. 20746. [Class 80 (ii)] [Also in Group XXIII In a copying machine such as a milling- machine, lathe &c. a driving shaft 70, Fig. 6, rotates a feed shaft 70a through a clutch comprising a cylindrical spring coil 92 attached at 99 to a flange 86 on the shaft 70 and at 101 to a sleeve 100 surrounding the coil. The coil is normally free from an inner sleeve 91 attached to the shaft 70a, but when its rotation with the shaft 70 is restrained it contracts and grips the sleeve 91 to drive the shaft 70a. This restraint is imposed by the friction of an outer sleeve 105 normally rotating with the shaft 70 but which may be held stationary by a belt 80 engaging a pulley 81 thereon. One end of the belt is attached to a stationary bracket 71 and the other end to an armature 78 passing through solenoids 74. 75. The solenoids are connected to the contacts 45, 46 so that they will be energized when the contact 35 engages either of them. A spring 76, normally raises the armature to apply the brake to the sleeve 05 and cause the shaft 70a to be driven but when the contact 35 engages either of the contacts 45, 46 for more than a brief time, thus causing a considerable " in " or " out " feed of the cutter, one of the solenoids 74, 75 will be energized to pull the armature downwards against the spring and release the brake, whereupon the clutch will be disengaged and the feed traverse will be stopped until the " in " or " out continuous feed has ceased. Repeated intermittent engagements of contact 35 with contacts 45, or 46 will cause slipping of the clutch and so slow down the traverse. A modified construction of clutch for use in a lathe, but having the same features as that shown in Fig. 6, is described.

Abstract: 1395814 Percussive drills ROBERT BOSCH GmbH 5 May 1972 [7 May 1971] 20961/72 Heading B4C In a percussive drill of the kind in which the tool spindle is reciprocated by interaction between notches on opposed annular discs carried by the spindle and housing respectively, one or more additional discs are arranged coaxially inside the housing disc angularly adjustably relative thereto to enable the frequency of the blows to be varied for various drill sizes and speeds. In both embodiments described, the teeth of the or each additional disc may be the same in number or different from those on the housing disc. They may be adjusted to be selectively aligned with or staggered relative to the latter. The additional disc(s) are fixed axially. In the arrangement shown, an additional disc 233 is rotatable with the spindle or is fixed but adjustable through a limited angle within the fixed housing disc 232. This rotation is, controlled in one embodiment, by a pin 254 having flats on its end 255 engageable in a keyhole slot 234<SP>1</SP>. It may be held withdrawn from the slot when the disc 233 rotates with the spindle and only the teeth of the housing disc are effective, be inserted as in Fig. 4a with its teeth in one position relative to those of the disc 232 or in the position of Fig. 4c, for a different position, the juxtapositioning of the inner and outer teeth giving different blow frequencies. In another embodiment Figs. 8-10 (not shown), a rotary handle lifts a stop out of a radial bore in the disc 233 to free it for rotation with the spindle. The housing disc may be angularly adjustable (not shown).

Filed: 1947-08-01
Abstract: 642,417. Telescopic umbrellas. LACHMANN, K. Aug. 1, 1947, No. 21056. [Class 134] The telescopic stick sections 1, 2 Fig. 1, are locked when extended by a nose 6, carried by a spring 8, in such manner that the nose has a limited axial movement in addition to the locking transverse movement so that it is subjected to shear stress by the extended stick sections and can be manually released by a slidable member 15 independently of the telescoping movement of the stick sections. In the preferred form, a U-shaped spring 8 of steel wire or strip, which carries the cylindrical inclined nose 6, is located within the section 2 by a projection 10 joined by the flanged edge of an aperture in the spring. Relative rotation of the stick sections 1, 2 is prevented by inter-engaging projection 4 and groove 3, and axial extension by the projections 4, 5. The member 15 is operated by a knob, Fig. 3 (not shown) projecting through the handle to which the section 2 is secured by a nut and a flanged bush; a pin through the section 3 bears against the inner end of the bush. The nut engages with a screw-thread cut on the corners only of a polygonal cross-section of the section 2. In a modification, the spring limb 28, Fig. 4, is longer than the limb 30, and a spring 32, bearing against the locking spring, serves to return the slidable member 33 to its inoperative position; the spring 32 is secured at 34 to the member 33 which is guided thereby when inserted into the section 2.
